APPARATUS FOR TREATING COATED FABRICS.

Application filed May 21,1914. Serial No. 840,111.

To all whom it may concern:

Be it known that I, CARL JOHN LANDIN,

a citizen of the United States, residing in Boston, in the county of Suffolk and State of Massachusetts, have invented an Improvement in Apparatus for Treating Coated Fabrics, of which the following description, in connection with the accompanying drawings, is a specification, likecharacters on the drawings representing like parts.

This invention relates to an apparatus for treating a strip or length of canvas or other material provided on one surface with a coating of adhesive material, whereby a predetermined length of the canvas layer is subjected to a moisture to render the canvas layer flexible and the coated surface of the same length is simultaneously subjected to a dry or substantially dry heat to render the coating layer tacky or sticky, so that opposite surfaces of a given length of the strip are put into a. condition to be applied to an inner sole of leather or other material and particularly to an inner sole having a lip and used in welted boots, and shoes.

The invention further has for its object to provide a simple and eflicient apparatus with which to treat coated layers of canvas or other fibrous material in accordance with my improved method. I

These and other features of this invention will be pointed out in the claims at the end of this specification.

Figure 1 is a side elevation of one form of apparatus embodying this invention. Fig. 2, a longitudinal section of the apparatus shown in Fig. 1. Fig. 3, a plan of the apparatus shown in Fig. 1. Fig. 4, a cross section on the line 44, Fig. 1. Fig. 5, a detail of the coated fabric, and Fig. 6, a modification to be referred to.

Referring to the drawing (1!, represents a strip or layer of canvas cloth or like mate rial having on one surface a coating layer 6 of adhesive material, see Fig. 5, such as now commonly used for aflixing the canvas layer a to leather or other inner soles of the Gem type. The coated layer a in accordance with this invention is passed between two members c, d, which are suitably constructed and arranged, so that the opposite surfaces of the canvas layer a are subjected simultaneously to moisture and to dryor substantially dry heat, whereby the canvas or fibrous layer a is exposed to moisture, which serves to render the fibrous layer flexible and pli- Specification of Letters Patent.

able so that it can be easily manipulated, and the coating 6 is simultaneously subjected to a dry or substantially dry heat, to render the coating layer tacky or sticky and in a condit-ign to adhere to a leather or other inner so e.

The member 0 for providing the moisture is herein shown as an oblong chest or cham' ber, which is closed at its bottom, sides and ends, and is provided with a perforated top 10, through which moist steam admitted into the chamber 0 may pass out therefrom. The moist steam may be circulated through the chamber a and for this purpose, the latter is provided in one of its side walls with ports 12, 18, with which suitable pipes 14, 15 are connected, one of said pipes as 14 being the exhaust pipe of an engine or other apparatus employing steam, while the other pipe 15 may lead to the outside of the building in which this apparatus is located and discharge into the atmosphere, or it may lead to any form of well or receptacle.

The heating member a? is located above the member 0 substantially parallel therewith and in close proximity thereto, being separated by a space 16 of sufficient depth to permit the coated strip or layer a to pass freely between the same in the direction of the length thereof.

The heating member d is herein shown as a hollow chamber or chest, which is provided with steam inlet and outlet pipes 20, 21, for live or substantially dry steam, and the wall of the chamber (Z which opposes the perforated wall of the chamber 0, is imperforate, so that a dry heat radiates from the same and acts upon the coating layer 6 to render the same tacky or sticky, and in condition to adhere to the leather or other inner sole, not shown. In the present instance, the heating member 61 is shown as supported at its opposite ends in an inclined position by uprights or standards 22, 23, one of which as 22 rests upon the fioor 24 and the other upon a work table 25.

The lower member 0 is supported by the secured in fixed relation thereto by set screws 31, see Fig. 4.

The hangers 26 are made long enough so that one or both of the side arms 29 thereof, 5 may be removed from the'member cl a dis tance substantially equal to the width of the member 0, so that the perforated top plate of the latter may be moved laterally from under the member d and into substantially 10 the position represented by the dotted lines in Fig. 4, to permit the coated strip or layer ato be placed in position on the member 0 and to permit it to be removed therefrom if desired, or to be inspected on said member. The member a is provided on its perforated surface 10 at its opposite sides, with ,guide strips 33 to keep the coated strip in proper position, as it is moved over the perforated surface 10. p

The guide strips 33 may be extended be yond the lower end of the member 0 and form bearings for a roller 35,,over which the coated strip or layer a is passed. The lower member 0 may have secured to it a hanger or support for the shaft or center pin 40 upon which the coated strip or layer in the form of a roll 41 is wound. The 'hanger referred to, is herein shown as a cross bar 42 provided with side arms 43, 80 which are notched or recessed for the reception of the journals of the shaft or pin 41. The upright or standards 22, 23 are preferably provided with curved feet 50, 51, provided with elongated slots 52 for the passage of screws or bolts 53, by means of which the feet are secured in fixed relation to the floor 24 and work table 25, and said feet are curved on their under surface to enable the heating member d to be given different inclinations to adapt the same to work tables at different heights above the floor, and yet provide for the bolts or screws 53 to secure a firm engagement of the feet with the floor and table, irrespective of the height of the 415 latter above the floor, within limits. 1

By making the perforated top 10 for the member 0 laterally movable with relation to said member, a plurality of perforated tops 10 may be used with a single chamber 0 as represented in Fig. 6, and the capacity of the apparatus increased, for while one per forated top plate 10 is in its operative position, the other is in its inoperative position and a second-coated strip narrower or wider 55 may be laid thereon ready to be used, when the desired length ofthe first strip has been put through the machine.

Inoperation with the apparatus herein shown, the coated strip or layer a passes from the roll 41 over the. roller 35 and between the members '0, d, to the table 25,

where the operator cuts the layer a into pieces of a width suitable to be applied to the inner sole. The coated layer a passes between the members with. the canvas layer layer 6 covering the same length of canvas is subjected to the action of a dry or substantially dry heat, which radiates from the bottom plate of the heating member d. In this manner, both layers of the coated fabric are simultaneously subjected to moisture and heat best adapted for placing the coated fabric in the best condition for use, inasmuch as the moisture imparts to the canvas layer the required or desired flexibility or pliability so that, it can be manipulated to conform to the shape of the inner sole, while the dry or substantially dry heat is best adapted to render the coating layer 7) in a tacky or sticky condition, best adapted for adhesion to the inner sole. In addition the apparatus is compact, substantially inexpensive and durable, and can be assembled in a substantially small space and requires a minimum care to maintain it in working a condition.

In the present instance, the moistening andheating members are arranged with the dry heating member superimposed over the moistening member, but it is not desired to limit the invention to this particular arrangement, as it may be reversed or they '100 may be arranged side by side. It is preferred however, to arrange the member as herein shown. It will be observed however, that a given or predetermined length of the coated fabric is simultaneously subjected to a moisture and dry or substantially dry heat on its opposite sides, so that, the fabric layer is subjected to moisture and the adhesive coating to heat in the absence of moisture, and it is not desired to limit the invention to the particular construction of apparatus hereinshown for effecting this result, although it may be preferred. The top wall 10 may be supported in its lateral movement by plates 60 which rest on the rods 30. For convenience in assembling the machine, the rods 30 which support the chamber 0 are adjustable in vertical slots 62 inthe arms 28, 29 of the hanger by the set screws 31.
